Which quality describes the speaker in this excerpt from Letters from a Cat by Helen Hunt Jackson? As soon as I heard Mary coming down the cellar stairs this morning, I hid in the arch, and while she was skimming the milk, I slipped upstairs, and ran into the sitting-room. Everything there is in the same confusion; the carpet is gone; and the windows too, and I think some of the chairs have been carried away. All the china is in great baskets on the pantry floor; and your father’s and mother's clothes are all taken out of the nursery closet, and laid on chairs. It is very dreadful to have to stand and see all this, and not be able to do anything. I don't think I ever fully realized before the disadvantage of being only a cat.
